-VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 733,940, dated July 21, `1903.

Application filed December 3, 1902. Serial No. 133,729. (No model.)

To 1f/ZZ whom, it jnlctyconcern: l

Be it known that I, FRANK BOSCH, a citizen of the United States, residing at Crescent City, in the county of Del Norte and State of California, have invented a new and useful Ve-I hicle, of which the following is a specification.

This invention relates to vehicles, and is particularly designed to provide improvements in the manner of mounting the bed or body shown in my prior patent, No. 697,395, dated April 8, 1902.

Itis furthermore designed to provide an improved standard for the support of each spring member upon the running-gear, so as to permit of a free vertical swinging movement of the spring.

Another object is to provide improvements in the manner of connecting the lower end of each spring member to the vehicle bed or body in order that the spring may have the desired lateral looseness.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described,'shown in theaccompanying drawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made Within the scope of the claims without departing from kthe spirit or sacricin g any ot' the advantagesof the invention.

In the drawings, Figure 1 is a side elevation of a vehicle-body and run ning-gear having the improved arrangement of supportingsprings applied thereto.

Fig. 3 is a detail perspective view of one of the standards. Fig. 4 is a detail perspective view of one of the brackets for attachment Fig. Zlis an inverted j bottom plan view of one end of the vehicle.

these parts may b e varied, as theyconstitute no part of thepresent invention.

In carrying out the present invention a standard3 is iitted to each end of the rear "axle andat both Vends` of the head-block of the front axle at the outer side of the wagonbed, the lower end of the standard being provided with an attaching-bracket consisting of a substantially horizontal arm 4, bent laterally inward and lying fiat upon the top of the axle, a cross-head member 5, integral with the outer end of the arm 4 and bolted to the top of the adjacent reach-bar of the running-gear, and a pendent member 6 at one end of the'part 5 and lying against and projected-below the axle, with its lower end prol vided with openings for the reception of a truss or tie-bar 7, which liesl below the reachbar,the opposite end of the tie-bar being connected lto the corresponding member 6 of the bracket at the opposite end of the vehicle. In addition to the bracket the standard is furthermore connected to the axle by means of an axle-clip 8, embracing the axle and the arm 4 close up to the standard. The upper end of the standard is reduced to form a bearing-spindle 8, at the base of which is an annular shoulder 9, the outer extremity of the spindle being reducedl and formed into a screw-threaded stem or projection 10. A

bracell extends between Ithe upper end portion of the standard and the adjacent reachbar. A tubular coupling or sleeve l2 rotatably embraces the spindle portion 8 of the standard and is supportedl upon the shoulder 9. This upstanding sleeve or coupling is provided with a horizontally-perforated ear 13 or bearing-knuckle, and a retaining-nut 14 is fitted to the screw-threaded projection 10, so as to prevent displacement of the coupling without interfering with the free rotation j hinged connection between the upper end of the spring member and the swiveled sleeve 12. lt will of course be understood that the bolts loosely pierce the followers and are provided at their screw-threaded ends with nuts to form heads, which bear against the outer faces of the followers, whereby when tension is placed upon the spring and the latter compressed thereby the followers may readily slide upon the bolts. For connecting the lower end of each spring member to the vehicle there is a bracket 22, consisting of a straight arm, which is bolted or otherwise secured to the under side of the bottom of the vehicle-body, is setat an angle to the axle, and has itsouter end projected beyond the adjacent side of the vehicle-body and provided with a spindle portion and a nut, as described, for the upper end of the standard. The outer end ofthe bracket is furtherbraced by means of a clip 23, which is secured to the under side of the vehicle-body and embraces the bracket-arm. A sleeve or coupling 24, having a perforate knuckle 25, is rotatably fitted to the spindle portion of the bracket 22 and is a substantial duplicate of the coupling 12, with the exception that the knuckle 2 5 stands substantially vertical instead of hori-` zontal. The eyes of the bolts or links 19 lie at the opposite ends of the knuckle 25 and are pivotally connected thereto by means of a bolt 26, wherebyit will be understood that the connection between the upper end of the spring and the standard is substantially the same as that between the lower end of the spring and the bracket upon the vehicle-body.

As best indicated in Fig. 2 of the drawings, it will be seen that the standards are located outwardly from the respective brackets of.` the Vehiclebody, whereby the springs are,l inclined inwardly toward the center of the; body, and hence exert radial pulls, thereby toi prevent lateral swaying of the vehicle-body, 3V while at the same time permitting of the desired vertical yielding movements when passvice may be conveniently assembled and fitted to the running-gear and the vehicle-body without requiring the employment of skilled labor.

What is claimed is- 1. A vehicle-spring, embodying a standard vhaving an upper terminal spindle portion, a

horizontal rotatable tubular coupling mounted upon the spindle and provided with asubstantially horizontal knuckle, a bracket for attachment to a vehicle-body and provided with an outer terminal spindle portion, a vertically-rotatable tubular coupling mounted upon the spindle portion of the bracket and provided with an upstanding knuckle, a helical spring interposed between the two couplings, two sets of eyebolts piercing the followers with their eyes embracing opposite ends of the respective knuckles, and pivotbolts extending through the corresponding eyes and knuckle.

2. The combination with a running-gear and avehicle-body, of a standard rising from one of the axles, and provided at its lower end with a lateral arm lying upon the top of the axle, a cross-head at the outer end of the arm and lying transversely across the axle` and longitudinally upon the top of the adjacent reach-bar, and a pendent member at one end of the cross-head and lying against l.

the outer side of the axle, a bracket carried by and projected laterally from the vehiclebody,and a spring connected at opposite ends to the standard and the bracket.

A vehicle-spring, embodying astandard having its lower end provided with a laterally-projected substantially T-shaped bracket member with a pendent member at one end of the bracket, the upper end of the standard havinga spindle portion with an annular shoulder at the base thereof and a reduced screw-threaded projection atits outer end, a tubular coupling rotatably mounted upon the spindle portion and supported upon the shoulder, theV coupling being provided with a substantially horizontal knuckle, a nut applied to the screw-threaded projection, a bracket for application to a vehiclebody,land `provided with a spindle portion having a reduced terminal screw-threaded,projection, a rotatable tubularcoupling mounted upon said spindle portion and provided with `an upstanding knuckle, a nut fitted toisaid screwthreaded projection, a helical spring interposed between the couplings, followers at opposite ends of the spring, two sets of eyebolts piercing the followers with their eyes registered with the opposite ends of the respective knuckles, and `pivot-bolts passing through the knuckles andthe respective eyes.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two witnesses.

FRANK BUSCH.
